Sorry for my English.
The problem not in autodetection stuff.

The problem is in fxp(4) dirver, that doesn't detect/show all available 
media types on the NIC. It shows only "media manual".

Other well supported Intel 82559-based PCI Card shows like that:

solik at solik$ ifconfig fxp0
fxp0: flags=9943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,LINK0,MULTICAST> 
mtu 1500
         options=8<VLAN_MTU>
         ether 00:03:47:e3:7d:c8
         media: Ethernet autoselect (100baseTX <full-duplex>)
         status: active
solik at solik$ ifconfig -m fxp0
fxp0: flags=9943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,LINK0,MULTICAST> 
mtu 1500
         options=8<VLAN_MTU>
         capabilities=8<VLAN_MTU>
         ether 00:03:47:e3:7d:c8
         media: Ethernet autoselect (100baseTX <full-duplex>)
         status: active
         supported media:
                 media autoselect
                 media 100baseTX mediaopt full-duplex
                 media 100baseTX
                 media 10baseT/UTP mediaopt full-duplex
                 media 10baseT/UTP
                 media none
                 media 100baseTX mediaopt hw-loopback


The autodetection problem solved easily with correct cable and setting 
switch to 'auto speed/auto duplex'.

However, it is not possible to select other than 'auto' mode on 
ICH7-based fxp1 interface, scince only 'manual' available.

That's my request for help - add support to fxp(4) for ICH7-based NIC 
for the full range of media types.

Excuse my English again, thanks!
